Description
Technical Field
[0001] The utility model relates to the technical field of detection devices, in particular to a flatness detection device for a PVC film. Background Art
[0002] The main component of PVC film is polyvinyl chloride, which is translucent and can be used alone or in the production of various composite papers. PVC film has the advantages of heat insulation, moisture resistance, and light weight. Therefore, it has been widely used in various industries. Due to different use environments, the manufacturing precision requirements for PVC film are also different. In some film-sticking fields with strict size requirements, the production quality requirements for PVC film are very strict. All PVC films need to be tested for flatness before leaving the factory.
[0003] Currently, most inspections are performed manually, or with manual auxiliary observation, which makes it too dependent on manpower and easily causes fatigue of workers. Utility Model Content
[0004] In view of the deficiencies of the prior art, the utility model provides a flatness detection device for PVC film, which overcomes the deficiencies of the prior art and effectively solves the problem that most of the prior art requires manual detection or manual auxiliary observation, which makes it too dependent on manpower and easily causes fatigue of workers.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A flatness detection device for a PVC film comprises a base plate, a first fixing plate being fixed at one end of the top of the base plate, and a second fixing plate being fixed at the other end of the top of the base plate, both ends of an outer wall of one side of the first fixing plate are rotatably connected to a rotating rod, and a first clamping block is fixed to one end of the rotating rod, both ends of an outer wall of one side of the second fixing plate are screwed with a handle screw, and one end of the handle screw is rotatably connected to a second clamping block, a detection mechanism is connected between the first fixing plate and the second fixing plate, and the detection mechanism comprises a symmetrically distributed fixing frame, a bidirectional screw rotatably connected to the inner walls at both ends of the fixing frame, an adjustment block respectively screwed to both ends of the outer wall of the bidirectional screw, and a detection rod rotatably connected to the outer wall of one side of the adjustment block.
[0007] The second clamping block is made close to the first clamping block by rotating the handle screw, so that the reel for conveying the PVC film is clamped between the first clamping block and the second clamping block, and the PVC film is passed through between the two detection rods, and the two adjusting blocks are driven by the rotating bidirectional screw rod to approach each other, so that the two detection rods are made close to each other and tightly attached to the two sides of the PVC film. When there are bulges on both sides of the PVC film, the two detection rods will be stuck with the bulges of the PVC film. As the PVC film is conveyed, the detection mechanism will be lifted upward, so that the detection mechanism will touch the push switch, thereby causing the buzzer to sound an alarm.
[0008] Preferably, a servo motor is installed on the top of the outer wall on the other side of the first fixing plate, and the output shaft of the servo motor is connected and fixed to one end of the rotating rod.
[0009] The servo motor drives the rotating rod to rotate, and the rotating rotating rod drives the first clamping block to rotate.
[0010] Preferably, a sliding groove is provided on one side outer wall of the first fixing plate and the second fixing plate, and sliding rods are fixed to the inner walls at both ends of the sliding groove.
[0011] The first fixing plate and the second fixing plate are both connected to the detection mechanism via a sliding rod.
[0012] Preferably, a push switch located above the slide slot is installed on the outer wall of one side of the first fixing plate, and the push switch is connected to a buzzer located on the outer wall of the other side of the first fixing plate via a wire.
[0013] After the detection mechanism moves upward and contacts the push switch, the buzzer sounds an alarm.
[0014] Preferably, a connecting block is fixed to the bottom of the outer wall of one side of the fixing frame away from the detection rod, and the connecting block forms a sliding fit with the sliding groove.
[0015] The connecting block moves upward in the slide slot, so that the detection mechanism moves upward and approaches the press switch.
[0016] Preferably, a through hole is provided on the top of the connecting block, and the through hole forms a sliding fit with the sliding rod.
[0017] The connecting block slides on the sliding rod through the through hole.
[0018] The beneficial effects of the utility model are:
[0019] The reel for conveying the PVC film is clamped between the first clamping block and the second clamping block, and the PVC film is passed between the two detection rods. The two adjusting blocks are driven by the rotating bidirectional screw rod to approach each other, so that the two detection rods are close to each other and tightly attached to the two sides of the PVC film. When there are bulges on both sides of the PVC film, the two detection rods will be stuck with the bulges of the PVC film. As the PVC film is conveyed, the detection mechanism will be lifted upward, so that the detection mechanism touches the push switch, thereby causing the buzzer to sound an alarm, which effectively solves the problem that most of the existing technologies are mostly detected manually, or auxiliary observation is performed manually, which makes over-reliance on manpower and easily causes fatigue of workers.

[0028] A push switch 8 located above the slide groove is installed on the outer wall of one side of the first fixed plate 2. The push switch 8 is connected to a buzzer located on the outer wall of the other side of the first fixed plate 2 through a wire. After the detection mechanism 11 moves up and abuts against the push switch 8, the buzzer sounds an alarm. A connecting block 13 is fixed to the bottom of the outer wall of the side of the fixed frame 12 away from the detection rod 16. The connecting block 13 forms a sliding fit with the slide groove.
